Hi,
I'm getting an error trying to run a codepy sample from the documentation:
http://documen.tician.de/pycuda/metaprog.html#metaprogramming-using-codepy
from codepy.cgen.cuda import CudaGlobalmod = Module([
Typedef(POD(dtype, "value_type")),
FunctionBody(
CudaGlobal(FunctionDeclaration(
Value("void", "add"),
[Pointer(POD(dtype, name)) for name in ["result", "op1", "op2"]])),
Block([
Initializer(
POD(numpy.int32, "idx"),
"threadIdx.x + %d*blockIdx.x" % (thread_block_size*block_size)),
]+[
Assign("result[idx+%d]" % (o*thread_block_size),
"op1[idx+%d] + op2[idx+%d]" % (
o*thread_block_size,
o*thread_block_size))
for o in range(block_size)
])
)
])
from pycuda.compiler import SourceModulemod = SourceModule(mod)
I'm receiving the following error:
In [3]: mod = Module([
...: Typedef(POD(dtype, "value_type")),
...: FunctionBody(
...: CudaGlobal(FunctionDeclaration(
...: Value("void", "add"),
...: [Pointer(POD(dtype, name)) for name in ["result", "op1",
"op2"]])),
...: Block([
...: Initializer(
...: POD(numpy.int32, "idx"),
...: "threadIdx.x + %d*blockIdx.x" %
(thread_block_size*block_size)),
...: ]+[
...: Assign("result[idx+%d]" % (o*thread_block_size),
...: "op1[idx+%d] + op2[idx+%d]" % (
...: o*thread_block_size,
...: o*thread_block_size))
...: for o in range(block_size)
...: ])
...: )
...: ])

NameError Traceback (most recent call last)
/home/prigor/projects/pycuda/pycuda-0.93/test/<ipython console> in
<module>()
*NameError: name 'dtype' is not defined*
Has anyone gotten this to work?
Thanks,
Paul
